What you need to know:

Travellers will be required to hold an Electronic Travel Authority, effective October 1, 2019

This includes travellers who are transiting through New Zealand, meaning even if New Zealand is not a traveller's final destination, they still must hold an ETA prior to entering the country

Travellers can apply for the ETA via the official mobile app or via a browser

The cost of an ETA obtained via the app is NZ$9 while obtaining an ETA via a standard web browser costs NZ$12

All international airline crew will be required to obtain an ETA at a set price of NZ$9

The standard passenger ETA is valid for two years, while a crew ETA is valid for five years

Travellers can begin applying for New Zealand's ETA on July 1, 2019

Australian citizens will not require an ETA - however, Australian permanent residents will

Other exemptions will apply to crew and passengers on a non-cruise vessel, crew on a foreign ship carrying cargo, guests of the government, people travelling under the Antarctic Treaty and members of a visiting force and associated crew members

The International Visitor Conservation and Tourism Levy will cost NZ$35

Travellers will be required to pay the new levy in conjunction with the new ETA requirement. The levy will be valid for the duration of the traveller's ETA.

Both the ETA and conservation and tourism levy will also be required for those arriving in New Zealand on a cruise ship.
